One thing I’m interested about the 4C is how much better the head tracking is? Is it the same as the eye position support of the EyeX? Or is it substantially better? Is there a new API for it or did the eye position accuracy just improve?
Head tracking data in 4C is different from 3d eyeball positions and is much more precise. Head tracking API is not yet publicly available but we are working hard to release it.
Currently you can test head tracking in some games (for example Elite Dangerous) using our Infinite Screen Extension.
